Hey People,
I am getting an Error 'You can't assign a value to this object.' when i am trying to update a text box value that has Control Source that is placed on a other form
Please guide me on the same

    If RVCalcCheck Then
     Me.ContractRemainingRV.Value = mdblOriginalRV - (Access.Nz(Me.txtRVTransfer.Value, 0#) + Access.Nz(Me.txtRVRecovery.Value, 0#))
        'Me.ContractRemainingRV.Value = mdblOriginalRV - Access.Nz(Me.txtRVTransfer.Value, 0#)
        'Me.ContractRemainingRV.Value = mdblOriginalRV - (Access.Nz(Me.txtRVRecovery.Value, 0#))
        Me.txtContractRemainingRV.Requery
        'DoCmd.RunCommand acCmdSaveRecord
    Else
        MsgBox "Remaining RV cannot be less than zero", vbExclamation, "RIMS"
        'Me.txtRVTransfer.Value = Me.txtRVTransfer.OldValue
    End If
  
 
 
 If Me.[ContractRemainingRV] - (Me.txtRVTransfer - Me.txtRVTransfer.OldValue) - Me.txtRVRecovery < 0 Then
       MsgBox "Remaining Rv cannot be less than zero!", vbCritical, "RIMS"
       Me.txtRVTransfer = Me.txtRVTransfer.OldValue
   Else
       Me.ContractRemainingRV = Me.ContractRemainingRV - (Me.txtRVTransfer - Me.txtRVTransfer.OldValue)
   End If

   Me.txtContractRemainingRV.Requery
    'DoCmd.RunCommand acCmdSaveRecord
    Forms!frmContractRewrite!txtRemainingRV.Value = val(Me.txtRVTransfer.Value) + Forms!frmContractRewrite!txtOldPVofRV.Value
    Forms!frmContractRewrite!txtRemainingRV.Requery
    strRewriteContractNOValue = ""

You dont specify which line is giving you an error, and you don't specify what the controlsource is. Please revise your question with the needed details.

[syedshaffee]

The Line is
Forms!frmContra ctRewrite!txtRe mainingRV.Value = val(Me.txtRVTra nsfer.Value) + Forms!frmContra ctRewrite!txtOl dPVofRV.Value

the ControlSource is containing calculation for a specific field

[TheSmileyCoder]

Only if the controlsource is directly bound to a field in a recordset can you update it (provided the recordset itself is updateably off course).
